(Pearce) OY Car eclipse

Further to my observation of the eclipse for OY Car last night, I have redone
the magnitude estimates utilising the Tycho-2 magnitudes of the OY Car Chart GIF
file on VSNET.  These magnitudes extend down to 12.0.  There is  a distinct
difference in the comparison star magnitudes between the Tycho-2 data and the
current comparison star mags I have on my chart.  Generally the Tycho-2 mags are
brighter.

There is a star NW of OY Car which has a magnitude of 12.5 which does not have a
corresponding Tycho-2 magnitude which has also been used for the estimates.

I hope to view further eclipses tonight.
